[0016] The following description, with reference to the accompanying drawings, is provided to aid in a comprehensive understanding of the various embodiments of this disclosure as defined by the appended claims and their equivalents. The various embodiments of this disclosure include a variety of specific details, but these details are to be considered exemplary only. Furthermore, for clarity and brevity, descriptions of well-known techniques, functions, and constructions may be omitted.

[0017] The terms and words used in this disclosure are not limited to their literal meanings, but are used solely by the inventors to ensure a clear and consistent understanding of the disclosure. Therefore, the descriptions of various embodiments of the disclosure provided are for illustrative purposes only and not for limiting purposes.

[0018] It should be understood that, unless the context clearly indicates otherwise, the singular forms “a,” “an,” “the,” and “the” used herein may also include the plural forms. It should be further understood that the word “comprising” as used in this disclosure means the presence of the described features, integers, steps, operations, elements, and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

These terms are only used to distinguish one element from another. Therefore, without departing from the teachings of the example embodiments, the first element discussed below may be referred to as the second element.

[0020] It should be understood that when an element is referred to as “connected” or “coupled” to another element, it can be directly connected or coupled to the other element, or there may be an intermediate element. Furthermore, the use of “connected” or “coupled” herein can include wireless connections or wireless couplings. The terms “and / or” or the expression “at least one of…” as used herein include any and all combinations of one or more of the associated listed items.

[0021] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains.

[0022] Figure 1 This illustrates an exemplary way of WLAN awareness.

[0023] The process of WLAN sensing can be as follows: the initiator initiates WLAN sensing (e.g., initiates a WLAN sensing session), and there may be multiple responders. Specific possible methods include... Figure 1 As shown in (a), (b) and (c) in the figure.

[0024] Reference Figure 1 In (a) of this clause, when a WLAN sensing initiator (e.g., a client) initiates WLAN sensing, multiple associated or unassociated WLAN sensing responders (e.g., three access points (APs)) can respond. Here, "associated" can refer to an association connection established between the initiator and the responder for communication, while "unassociated" can refer to an association connection not established between the initiator and the responder for communication.

[0025] As an example, a client may include, but is not limited to: cellular phones, smartphones, wearable devices, computers, personal digital assistants (PDAs), personal communication system (PCS) devices, personal information managers (PIMs), personal navigation devices (PNDs), global positioning systems, multimedia devices, Internet of Things (IoT) devices, etc.

[0026] An Access Point (AP) is a wireless switch used in a wireless network, and also an access device for the wireless network. An AP may include software applications and / or circuitry to enable other types of nodes in the wireless network to communicate with the outside and inside of the wireless network. As an example, an AP can be a terminal device or network device equipped with a Wi-Fi (Wireless Fidelity) chip.

[0027] Figure 1 (b) and Figure 1 Similar to (a) in, but in Figure 1 In (b) of the above, the various responders (APs) can communicate with each other.

[0028] Reference Figure 1 In (c), both the WLAN sensing initiator and the WLAN sensing responder can be clients, and they can communicate by connecting to the same AP.

[0029] Although Figure 1 As shown in (a), (b), and (c) above, the client acts as the initiator and the AP as the responder; however, this disclosure is not limited thereto. For example, the AP can act as the initiator and the client as the responder. Furthermore, the number of initiators and responders is not limited to [specific details needed]. Figure 1 As shown in (a), (b) and (c) in the figure.

[0030] The WLAN sensing session initiated by the initiator (i.e., the WLAN sensing process) may include: the establishment of the WLAN sensing session, the establishment of WLAN sensing measurements, and the termination of WLAN sensing measurements.

[0031] During the establishment of a WLAN sensing session, the sensing session is established, and the operational parameters associated with the sensing session are determined and exchanged between the devices (initiator and responder). During the establishment of a WLAN sensing measurement, a sensing measurement procedure can be established and executed during the procedure. During the termination of a WLAN sensing measurement, the device stops performing measurements and terminates the sensing session.

[0032] In a sensing session, one or more sensing measurements can be established (i.e., one or more sensing measurement procedures can be established), and each sensing measurement procedure can contain at least one sensing measurement event. Within each sensing measurement event, sensing measurements can be performed between an initiator and a responder. Here, the initiator can initiate a sensing measurement event and receive sensing measurement feedback, while the responder can provide feedback on the sensing measurement results to the initiator. For example, sensing measurement feedback can occur after each sensing measurement event, known as timely feedback, or the results can be provided after all or part of the sensing measurement events have been completed, known as delayed feedback.

[0033] For delayed feedback, the sensing measurement results established by multiple sensing measurements from the sensing responder can be included in a single measurement report frame for delay reporting. According to embodiments of this disclosure, each of the multiple sensing measurement results included in the single measurement report frame can include channel state information (CSI). For example, the initiator can support obtaining multiple sensing measurement results from a single measurement report frame sent by the responder, and / or the responder can support caching multiple sensing measurement results and sending them to the initiator in a single measurement report frame. That is, multiple sensing measurement results can be aggregated into a single measurement report frame for feedback; however, currently, a mechanism is lacking for how the initiator can activate the responder to send a measurement report frame.

[0034] In view of the above, a communication method and a communication device are provided according to the concept of embodiments of the present disclosure to at least solve the above-mentioned technical problems.

[0035] Figure 2 This is a flowchart illustrating a communication method according to an example embodiment. Figure 2 The communication method shown can be a method performed by the initiator of WLAN sensing measurements.

[0036] Reference Figure 2 In step 210, a trigger frame can be determined, which may include information about multiple sensing measurement events for which feedback of sensing measurement results is required, wherein the multiple sensing measurement events correspond to at least one sensing measurement process. In other words, the information in the trigger frame can instruct feedback of multiple sensing measurement events for at least one sensing measurement process. Furthermore, for ease of description, the sensing measurement results may be simply referred to as "measurement results" in the following text.

[0037] In the embodiments of this disclosure, there can be many ways to determine the trigger frame. For example, the trigger frame can be generated or configured based on at least one of the following: channel state, network conditions, load conditions, hardware capabilities of the transmitting / receiving devices, service type, and relevant protocol specifications; this disclosure does not impose specific limitations on this. In the embodiments of this disclosure, the trigger frame can also be obtained from an external device, and this disclosure does not impose specific limitations on this. Furthermore, although the embodiments of this disclosure use a trigger frame to trigger feedback on the measurement results, this disclosure is not limited to this. For example, feedback on the measurement results can be requested using other message frames. For example, the trigger frame in step 210 can be replaced with, for example, a measurement report request frame.

[0038] In step 220, a trigger frame may be sent. For example, the initiator may send a trigger frame (or measurement report request frame) to the responder to instruct the responder to provide feedback on the measurement results (CSI) of the multiple sense measurement events identified in the trigger frame.

[0039] In one embodiment of this disclosure, the trigger frame determined in step 210 may correspond to a delayed feedback operation, and the device (initiator) sending the trigger frame supports the delayed feedback operation, and this support is in place during the sensing measurement session establishment process (e.g., referring to...). Figure 1 This is determined in the "establishment of a WLAN sensing session" in the described embodiments. For example, the ability of the device sending the trigger frame (the initiator) to support delayed feedback operations can be identified in the sensing measurement parameter information element and needs to be determined during the establishment of the sensing measurement session.

[0040] In one embodiment of this disclosure, the information in the trigger frame determined in step 210 may include: at least one sensing measurement establishment identifier corresponding to at least one sensing measurement process, and an identifier for at least one sensing measurement event corresponding to each sensing measurement establishment identifier among a plurality of sensing measurement events. The at least one sensing measurement establishment identifier may correspond to at least one sensing measurement process, and each sensing measurement process may include at least one (or more) sensing measurement events. The at least one sensing measurement event corresponding to each sensing measurement establishment identifier may be identified in different ways.

[0041] In one embodiment of this disclosure, the information in the trigger frame determined in step 210 may include: at least one perception measurement establishment identifier corresponding to at least one perception measurement process, and an identifier for at least one perception measurement event corresponding to each perception measurement establishment identifier among a plurality of perception measurement events. The identifier for the at least one perception measurement event corresponding to each perception measurement establishment identifier may include: at least one perception measurement event reporting identifier corresponding to each of the at least one perception measurement events.

[0042] In embodiments of this disclosure, the information in the trigger frame can indicate feedback for multiple sensing measurement events in a sensing measurement process. In this case, a measurement process may include multiple sensing measurement events, and the measurement results of the multiple sensing measurement events may be delayed feedback. Then, the format of the trigger frame (measurement report request frame) can be as shown in Table 1 below.

[0043] Table 1

[0044] Measurement setup ID Instance ID1 report Instance ID2 report …

[0045] In Table 1, the Measurement setup ID can refer to the sensing measurement setup identifier in the trigger frame, used to identify the sensing measurement process. Instance ID1 report and Instance ID2 report, etc., can refer to the identifiers of the first and second sensing measurement events corresponding to the sensing measurement setup identifier, respectively. That is, the sensing measurement process corresponding to the sensing measurement setup identifier Measurement setup ID can include the first sensing measurement event, the second sensing measurement event, etc. When the trigger frame contains the information shown in Table 1, it can indicate that the measurement results need to be fed back for the first sensing measurement event, the second sensing measurement event, etc. in this sensing measurement process (e.g., indicating the CSI of each sensing measurement event).

[0046] In embodiments of this disclosure, the information in the trigger frame may indicate feedback for multiple sensing measurement events in multiple sensing measurement processes. In this case, the multiple sensing measurement processes may include multiple sensing measurement events, and each sensing measurement process may include at least one sensing measurement event. The format of the trigger frame (measurement report request frame) may be as shown in Table 2 below.

[0047] Table 2

[0048]

[0049] In Table 2, Measurement setup ID1, Measurement setup ID2, etc., can refer to the sensing measurement setup identifier in the trigger frame, used to identify the first sensing measurement process, the second sensing measurement process, etc. Instance ID11 report and Instance ID12 report, etc., corresponding to Measurement setup ID1, can refer to the identifiers of the first and second sensing measurement events corresponding to the sensing measurement setup identifier Measurement setup ID1 (first sensing measurement process); Instance ID21 report, etc., corresponding to Measurement setup ID2, can refer to the identifiers of the sensing measurement events corresponding to the sensing measurement setup identifier Measurement setup ID2 (second sensing measurement process). That is, the first sensing measurement process corresponding to the sensing measurement setup identifier Measurement setup ID1 can include two or more sensing measurement events, and the sensing measurement process corresponding to Measurement setup ID2 can include one or more sensing measurement events, etc. When the trigger frame contains the information shown in Table 2, it can indicate that feedback of measurement results is required for the first sensing measurement event, the second sensing measurement event, etc., in the first sensing measurement process, and the sensing measurement events in the second sensing measurement process (e.g., indicating feedback of the CSI for each sensing measurement event).

[0050] According to one embodiment of this disclosure, the identifier of at least one sensing measurement event corresponding to each sensing measurement establishment identifier can be identified in a manner different from Tables 1 and 2.

[0051] The information in the trigger frame determined in step 210 may include: at least one perception measurement establishment identifier corresponding to at least one perception measurement process, and an identifier for at least one perception measurement event corresponding to each perception measurement establishment identifier among multiple perception measurement events. The identifier for each perception measurement establishment identifier may include: a perception measurement event start report identifier and a number of perception measurement events, wherein the perception measurement event start report identifier indicates the initial perception measurement event for which measurement results need to be fed back, and the number of perception measurement events indicates the number of perception measurement events since the initial perception measurement event.

[0052] For example, when the information in the trigger frame can indicate feedback for multiple sensing measurement events in a sensing measurement process, the format of the trigger frame (measurement report request frame) can be as shown in Table 3 below. For simplicity, descriptions of the same identifiers as those in Tables 1 and 2 are omitted in the following description.

[0053] Table 3

[0054] Measurement setup ID Instance ID starting report Number of instances

[0055] Referring to Table 3, "Instance ID starting report" can refer to the identifier for the start of a sensing measurement event, and "Number of instances" can refer to the number of sensing measurement events. For example, when the trigger frame contains the information shown in Table 3, it can instruct the responder to provide feedback on measurement results (e.g., CSI) for multiple consecutive sensing measurement events corresponding to the Measurement setup ID. For example, the starting sensing measurement event for multiple consecutive sensing measurement events can be identified by "Instance ID starting report," and "number of instances" can indicate the number of subsequent measurement events. For example, when "Instance ID starting report" identifies the first sensing measurement event in the sensing measurement process, and "number of instances" indicates a quantity of 2, it can instruct the feedback of measurement results for the first to third sensing measurement events in the sensing measurement process.

[0056] For example, when the information in the trigger frame can indicate feedback for multiple sensing measurement events in multiple sensing measurement processes, the format of the trigger frame (measurement report request frame) can be as shown in Table 4 below.

[0057] Table 4

[0058]

[0059] Referring to Table 4, it shows the sensing setup identifiers such as Measurement setup ID1 and Measurement setup ID2 corresponding to two (or more) sensing measurement processes, as well as the sensing measurement event start report identifier (Instance ID starting report) and the number of sensing measurement events (Number of instance) corresponding to each sensing measurement setup identifier. The sensing measurement event start report identifier (Instance ID starting report) and the number of sensing measurement events (Number of instance) in Measurement setup ID1 and Measurement setup ID2 may be different; however, this disclosure is not limited thereto.

[0060] The perception measurement setup identifiers Measurement setup ID1 and Measurement setup ID2 in Table 4, along with their corresponding perception measurement event starting report identifiers (Instance ID starting report) and the number of perception measurement events (Number of instances), can be similar to those in Table 3. Repeated descriptions are omitted here to avoid redundancy.

[0061] Furthermore, although Tables 3 and 4 show that each perception measurement establishment identifier contains only one perception measurement event start report identifier (Instance ID starting report) and its corresponding number of perception measurement events (Number of instances), this disclosure is not limited to this. For example, each perception measurement establishment identifier may contain more than one different perception measurement event start report identifier and its corresponding number of perception measurement events.

[0062] It will be understood that the formats of the trigger frames shown in Tables 1 to 4 (the information included in the trigger frames) are merely exemplary, and this disclosure is not limited thereto. Some content in Tables 1 to 4 may be omitted. For example, in Table 4, when the sensing measurement event start report identifier and the number of sensing measurement events corresponding to Measurement setup ID1 and Measurement setup ID2 are the same, the sensing measurement events corresponding to both Measurement setup ID1 and Measurement setup ID2 can be identified by a single sensing measurement event start report identifier and the number of sensing measurement events. Alternatively, some content in Tables 1 to 4 may be combined. For example, in Tables 3 or 4, at least one sensing measurement event can be identified for Measurement setup ID1 using the format shown in Table 1, while at least one sensing measurement event can be identified for Measurement setup ID2 using the format shown in Table 3. Tables 1 to 4 may also include other additional content.

[0063] According to one embodiment of this disclosure, Figure 2 The communication method illustrated can be performed by an access point device (AP). For example, the device that determines and sends the trigger frame (the initiator) can be the access point device (AP). In this case, the information in the trigger frame, in addition to the information shown in any of the embodiments described with reference to Tables 1 to 4, may also include identifiers of one or more stations participating in at least one sensing measurement process. That is, the access point device can send the trigger frame to multiple stations to instruct the multiple stations to report measurement results (e.g., CSI) for multiple sensing measurement events.

[0064] One or more stations participating in at least one sensing measurement process can be identified in different ways. According to embodiments of this disclosure, the identifier of one or more stations included in the trigger frame may include at least one of the following:

[0065] The identifier (AID) of the site that establishes an association communication with the access point device;

[0066] Identifier (UID) of a site that has not established an association with the access point device;

[0067] The site's MAC (Media Access Control) address.

[0068] For example, if the device sending the trigger frame (the initiator) is an access point device and indicates a station, the above Tables 1 to 4 can be transformed into Tables 5 to 8 below, respectively.

[0069] Table 5

[0070] AID / UID / MAC Measurement setup ID Instance ID1 report Instance ID2 report …

[0071] Table 6

[0072]

[0073] Table 7

[0074] AID / UID / MAC Measurement setup ID Instance ID starting report Number of instances

[0075] Table 8

[0076]

[0077] Tables 5 through 8 contain the same information as Tables 1 through 4, except for the AID / UID / MAC identifier for the site. Repeated descriptions are omitted here to avoid redundancy.

[0078] However, the trigger frames shown in Tables 5 to 8 are merely exemplary, and this disclosure is not limited thereto.

[0079] According to one embodiment of this disclosure, in addition to the information shown in any of the embodiments described with reference to Tables 5 to 8, the information in the trigger frame may also include: a communication resource unit (RU, radio unit) allocated for the feedback of the sensing measurement result of each sensing measurement event. For feedback of different sensing measurement events, the size of the RU allocated by the AP for the feedback of the sensing measurement event can be different or the same. By setting the RU required for feedback of each sensing measurement event in the trigger frame, communication resources can be rationally allocated, allowing the receiver to use the set RU to provide feedback on the corresponding sensing measurement event, avoiding interference between devices.

[0080] For example, when the device sending the trigger frame (the initiator) is an access point device and instructs one or more stations to simultaneously report multiple measurement results, the trigger frame may have the format shown in Tables 9 to 12 below.

[0081] Table 9

[0082]

[0083] Table 10

[0084]

[0085] Table 10 (continued)

[0086]

[0087] Table 11

[0088]

[0089] Table 12

[0090]

[0091] Table 12 (continued)

[0092]

[0093] Tables 9 through 12 illustrate examples of APs instructing at least one site to provide feedback on measurement results (e.g., Tables 9 and 11 correspond to the case of one site, and Tables 10 and 12 correspond to the case of two sites). Furthermore, while Tables 9 through 12 show one sensing measurement setup identifier per site, this disclosure is not limited to this; each site may correspond to more sensing measurement setup identifiers. Additionally, Tables 10 through 12 show RUs corresponding to sensing measurement setup identifiers (e.g., RU for measurement setup ID, RU for measurement setup ID1, RU for measurement setup ID2, etc.), which may indicate that the RU assigned to the sensing measurement event corresponding to the respective sensing measurement setup identifier is the same. However, this disclosure is not limited to this; for example, the RUs assigned to each sensing measurement event may be different. For instance, the RUs in Tables 10 through 12 may be set to correspond to sensing measurement events (e.g., similar to RU for Instance ID1, RU for Instance ID2, etc. shown in Table 9).

[0094] According to one embodiment of this disclosure, Figure 2 The communication method shown can be used by a non-access point device (non-AP, for example, Figure 1 The client in the process performs actions such as determining and sending trigger frames. The device (initiator) can be a non-access point device. In this case, due to the capability limitations of the non-access point device, it can only send trigger frames as shown in Tables 1 to 4 to one responder and receive feedback (CSI) from it for multiple sensed measurement events.

[0095] According to embodiments of this disclosure Figure 2 The communication method shown and the trigger frames described with reference to Tables 1 to 12 can trigger the transmission of measurement report frames that include multiple measurement results, saving resource overhead.

[0096] Figure 3 This is a flowchart illustrating another communication method according to an example embodiment. Figure 3 The communication method shown can be a method performed by the responder of WLAN sensing measurement.

[0097] Reference Figure 3 In step 310, a trigger frame is received, wherein the trigger frame may include information about multiple sensing measurement events for which sensing measurement results need to be fed back, and the multiple sensing measurement events correspond to at least one sensing measurement process. In step 320, the sensing measurement results of the multiple sensing measurement events are fed back based on the trigger frame. For example, the responder may feed back the CSI of the identified multiple sensing measurement events by sending a measurement report frame based on the information in the trigger frame.

[0098] According to one embodiment of this disclosure, the information in the received trigger frame may include: at least one perception measurement establishment identifier corresponding to at least one perception measurement process, and an identifier for at least one perception measurement event corresponding to each perception measurement establishment identifier among a plurality of perception measurement events. The identifier for the at least one perception measurement event corresponding to each perception measurement establishment identifier may include: at least one perception measurement event reporting identifier corresponding to each of the at least one perception measurement event.

[0099] According to one embodiment of this disclosure, the information in the received trigger frame may include: at least one perception measurement establishment identifier corresponding to at least one perception measurement process, and an identifier for at least one perception measurement event corresponding to each perception measurement establishment identifier among a plurality of perception measurement events. The identifier for each perception measurement establishment identifier may include: a perception measurement event start report identifier and a number of perception measurement events, wherein the perception measurement event start report identifier indicates the initial perception measurement event for which perception measurement results need to be fed back, and the number of perception measurement events indicates the number of perception measurement events since the initial perception measurement event.

[0100] According to one embodiment of this disclosure, when the trigger frame is received from an access point device, the information in the trigger frame, in addition to the information shown in any of the embodiments described with reference to Tables 1 to 4, may also include: identifiers of one or more stations participating in at least one sensing measurement process. For example, as described with reference to any of the embodiments in Tables 5 to 8, the identifiers of one or more stations may include at least one of the following: identifiers of stations that have established association communication with the access point device; identifiers of stations that have not established association communication with the access point device; and the MAC address of the station.

[0101] According to one embodiment of this disclosure, in addition to the information shown in any of the embodiments described with reference to Tables 5 to 8, the information in the trigger frame may also include: a communication resource unit that feeds back the perception measurement result allocation for each perception measurement event, for example, as described in any of the embodiments in Tables 9 to 12.

[0102] According to embodiments of this disclosure, the trigger frame corresponds to a delayed feedback operation, and the device receiving the trigger frame supports the delayed feedback operation, which is determined during the establishment of the sensing measurement session.

[0103] The embodiments of the trigger frames and the information they include, described above with reference to Tables 1 to 12, can be applied here; for the sake of brevity, repeated descriptions are omitted here.

[0104] According to embodiments of this disclosure Figure 3 The communication method shown and the trigger frames described with reference to Tables 1 to 12 can trigger the transmission of measurement report frames that include multiple measurement results, saving resource overhead.

[0106] Figure 4 The communication device 400 can be used as the initiator of WLAN sensing measurement. In this case, the processing module 410 can be configured to: determine a trigger frame, wherein the trigger frame may include information of multiple sensing measurement events for which sensing measurement results need to be fed back, and the multiple sensing measurement events correspond to at least one sensing measurement process; the transceiver module 420 can be configured to: send the trigger frame.

[0107] In other words, Figure 4 The communication device 400 shown can perform the reference Figure 2 The communication method described above, and the embodiments regarding the trigger frame and the information it includes (Tables 1 to 12) described above, can be applied here. To avoid redundancy, repeated descriptions are omitted here.

In this case, the transceiver module 420 can be configured to: receive a trigger frame, wherein the trigger frame may include information of multiple sensing measurement events for which sensing measurement results need to be fed back, and the multiple sensing measurement events correspond to at least one sensing measurement process; the processing module 410 can be configured to: control the transceiver module 420 to feed back the sensing measurement results of the multiple sensing measurement events based on the trigger frame.
